FAQs

Q1: How do I verify if this TA3103 CHRA fits my Komatsu PC150-3? 

Please check the nameplate on your turbocharger's compressor housing for the part number 6207-81-8240 or 465636-5217S. Since the 4D95L engine has several variations, matching the 10-digit Komatsu or 10-digit Garrett part number is essential. If unsure, provide your Machine Serial Number for a free fitment audit.

Q2: Is this cartridge pre-balanced and ready to install? 

Yes. Every Zhongke CHRA is VSR balanced at high speeds. It is a complete, pre-assembled internal unit that is ready for immediate installation into your original turbine and compressor housings. This ensures quiet operation and prevents premature bearing failure.

Q3: What makes Zhongke’s cartridges reliable for earthmoving work? 

Earthmoving equipment faces constant high vibration and load changes. We use genuine K18 nickel-alloy wheels and precision-machined bearings to ensure our cores can handle the thermal stress and high vibration of Komatsu machinery without premature failure.

Q4: What type of warranty do you provide for industrial-grade parts? 

As a direct manufacturer with nearly 30 years of experience, we stand behind our quality and provide full technical support for equipment owners and maintenance fleets worldwide.

Q5: Do you provide worldwide shipping? What is the delivery timeframe? 

We ship globally via premium carriers like DHL, FedEx, and UPS, as well as sea freight for bulk orders. In-stock items are typically dispatched within 24–48 hours. Express delivery to North America and Europe usually takes 5–7 business days.
